2019 MERCEDES-BENZ AMG GT ROADSTER hood release

Replacing the wiper blades
Important safety notes G
WARNING
If the windshield wipers begin to move while
you are changing the wiper blades, you could be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windshield wipers and
ignition before changing the wiper blades.
! Never open the hood if a windshield wiper
arm has been folded away from the wind-
shield.
Never fold a windshield wiper arm without a
wiper blade back onto the windshield.
Hold the windshield wiper arm firmly when
you change the wiper blade. If you release the
windshield wiper arm without a wiper blade
and it falls onto the windshield, the windshield may be damaged by the force of the impact.
Mercedes-Benz recommends that you have
the wiper blades changed at a qualified spe-
cialist workshop.
! To avoid damaging the wiper blades, make
sure that you touch only the wiper arm of the
wiper.

Proceed as follows:
R if you live in Canada.
R if you have difficulties programming the
garage door opener (regardless of where you
live) when following the programming steps.
X Press and hold one of buttons 0044to0085 on the
integrated garage door opener.
After a short time, indicator lamp 0043lights up
yellow.
X Release the button.
Indicator lamp 0043flashes yellow.
X Press button 0084of garage door remote con-
trol 0083for two seconds, then release it for two
seconds.
X Press button 0084again for two seconds.
X Repeat this sequence on button 0084of remote
control 0083until indicator lamp 0043lights up
green.
When indicator lamp 0043lights up green: pro-
gramming is finished.
When indicator lamp 0043flashes green: pro-
gramming was successful. The next step is to
synchronize the rolling code.
X Release button 0084of remote control 0083of the
garage door drive.
When indicator lamp 0043lights up red: repeat
the programming process for the correspond- ing button on the rear-view mirror. When
doing so, vary the distance between remote
control 0083and the rear-view mirror.
The required distance between remote con-
trol 0083and the integrated garage door opener
depends on the garage door drive system.
Several attempts might be necessary. You
should test every position for at least
25 seconds before trying another position.
Problems when programming If you are experiencing problems programming
the integrated garage door opener on the rear-
view mirror, take note of the following instruc-
tions:
R Check the transmitter frequency used by
garage door drive remote control 0083and
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remote control 0083for the garage door drive.
The integrated garage door opener is com-
patible with devices that have units which operate in the frequency range of 280 to
433 MHz.
R Replace the batteries in garage door remote
control 0083. This increases the likelihood that
garage door remote control 0083will transmit a
strong and precise signal to the integrated
garage door opener.
R When programming, hold remote control 0083
at varying distances and angles from but-
tons 0044to0085 which you are programming. Try
various angles at a distance between 2and
8 inches (5to 20 cm) or at the same angle but at varying distances.
R If a further remote control 0083is available for
the same garage door drive, repeat the same
programming steps with this remote control
0083. Before performing these steps, make sure
that new batteries have been installed in
garage door drive remote control 0083.
R Note that some remote controls only transmit
for a limited amount of time (the indicator
lamp on the remote control goes out). Press
button 0084on remote control 0083again before
transmission ends.
R Align the antenna cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.
Opening/closing the garage door After it has been programmed, the integrated
garage door opener performs the function of the garage door system remote control. Please also
read the operating instructions for the garage
door system.
X Select key position 0048with the Start/Stop
button (Y page 111).
X Press button 0044,0087or0085 which you pro-
grammed to operate the garage door.
Garage door system with a fixed code: indi-
cator lamp 0043lights up green.
Garage door system with a rolling code: indi-
cator lamp 0043flashes green.
The transmitter will transmit a signal as long
as the button is pressed. The transmission is
halted after a maximum of ten seconds and
indicator lamp 0043lights up yellow.
X Press button 0044,0087or0085 again if necessary. Features

Closing the hood G
WARNING
When opening and closing the hood, it may
suddenly fall into the closed position. There is a risk of injury to persons within range of
movement of the hood.
Open and close the hood only when no one is
within its range of movement.
X Lower the hood and let it fall from a height of
approximately 8 in (20 cm).
X Check that the hood has engaged properly.
If the hood can be raised slightly, it is not
properly engaged. Open it again and close it
with a little more force. Engine oil
Notes on the oil level Depending on your driving style, the vehicle
consumes up to 0.9 US qt (0.8 liters) of oil per
600 miles (1,000 km). The oil consumption may
be higher than this when the vehicle is new or if
you frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may be in a different location.
It is only possible to correctly measure the oil
level when:
R the engine is at normal operating temperature
R the vehicle is parked on a level surface
R the engine is left running in neutral for at least
30 seconds before switching off
This applies when checking the oil level using
the oil dipstick or on-board computer.
Checking the oil level using the oil dip-
stick G
WARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.
It is only possible to correctly measure the oil
level with the oil dipstick when the engine is at
normal operating temperature and in a period of 2 to minutes after the engine has been switchedoff. 236

WARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following. G
WARNING
Opening the hood when the engine is over-
heated or when there is a fire in the engine
compartment could expose you to hot gases
or other service products. There is a risk of
injury.
Let an overheated engine cool down before
opening the hood. If there is a fire in the
engine compartment, keep the hood closed
and contact the fire department. G
WARNING
The cooling system is pressurized, particularly when the motor is warm. If you open the cap, you could be scalded if hot coolant sprays out.
There is a risk of injury.
Let the engine cool down before you open the
cap. Wear protective gloves and protective
eyewear when opening. Open the cap slowly
to release pressure.
! Before starting your journey, make sure that
all engine covers are installed. Otherwise, the engine can be damaged, e.g. through over-
heating. Example
X Park the vehicle on a level surface.
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
X Select key position 0048with the Start/Stop
button.
X Check the coolant temperature display in the
instrument cluster.
The coolant temperature must be below
158 ‡ (70 †).
X Select key position 0092with the Start/Stop
button.
X Remove engine cover 0043upwards on both
sides.
X Slowly turn cap 0044half a turn counter-clock-
wise to allow excess pressure to escape.
X Turn cap 0044further counter-clockwise and
remove it.
If the coolant is at the level of the marker bar in the filler neck when cold, there is enough
coolant in coolant expansion tank 0087.
If the coolant level is approximately 0.6 in
(1.5 cm) above the marker bar in the filler
neck when warm, there is enough coolant in
coolant expansion tank 0087.
X If necessary, add coolant that has been tested
and approved by Mercedes-Benz. Engine compartment
